14 Claims.

This invention relates to tctaliz'in'g'devices and is especially usefulin the packing of eggs.

It has been found advantageous, in packing eggs for the retail market,to entrust the packer with the function of performing a iinalsegregation of the eggs after these have been sized and at the time sheis handling the eggs incidental to placing them in cartons. Counting theeggs as they are sized vfails to take into account this na-l segregationand thus fails to aiord a correct basis for compensating the farmer forthe eggs in each lot purchased from him.

It is an object of this invention to provide an egg totalizer whichtotalizes all the eggs in each of the various grades contained in aparticular lot 4and which does this las they are being packed.

It is another object of this invention to provide an egg `totalizerwhich totalizes the veggs packed in each grade from a Agiven lot byautomatically responding to the delivery of each packed carton of saidgrade to a conveyor belt and to the setting of said totalizer toindicate the number of eggs amounting to less than a full carton whichare packed from said lot in said grade at the completion of the packingof the eggs from said lot.

It is still another object of this invention to provide an egg totalizerwhich totalizes the eggs actually packed from a given lot .in each ofthe various grades and which requires a relatively small amount ofattention from the packer in order for this totalizer to accuratelyperform its functions.

The manner of accomplishing the foregoing objects a's well as furtherobjects and advantages will be made manifest in the followingdescription taken in connection with the accompanying drawings in which:

Fig. 6 is an enlarged sectional view taken on 'the lmet-5 of Fig. 4.

Fig. Tis a diagrammatic perspective view of the part carton counterswitch.

Fig. 8 is a diagrammatic View illustrating the mechanism and wiringsystem of one of said units.

Referring specifically to the drawings, Fig. 1 shows a packing apparatusl0 which includes a loose-egg conveyor il having an endless belt 12, theupper run of which constantly moves at a slow rate of speed towards afront wall I3, the conveyor i i having side walls lll and longitudinaldivision boards i5 which divides the space above the belt "I2 into fourlanes l, Il, i8 and 1'9.

Eggs delivered to the belt i2 are pre-sized into small, medium, largeand jumbo sizes and the eggs in each of these sizes are delivered to oneof these lanes. l

Immediately above the loose egg conveyor H is a packing table 25 onwhich a number 'of recesses *26- are provided for receiving six emptyegg cartons 2l.

Carried on the table 25, passing directly be'- hind the cartons 2, is apackedcarton conveyor belt 23. Provided on the table 25, 'beneath eachof the recesses E6, is a normally closed primary control 'startingswitch 29 having an actuating arm S'which normally extends upwardly intothe cavity in the bottom 'of the 'carton 27 resting lin said recess sothat when said carton has vbeen lled and is shifted rearwardly onto thebelt 28, the arm 35 is depressed and the 4switch 29 is mo# mentarilyopened.

Spaced above the packing table 25 is an undergrade table 3l on which aconveyor belt 32 travels lengthwise, the table 3l having racks 33 forsupporting ats 3ft, each of which is adapted to receive three dozenundergrade eggs. The conveyor Y32 is for carrying away the ats 34 whenthese have been lled.

. Disposed between the tables 2t and 3i is a totalizer table 4S on whichis mounted a series of totalizer units 4l, one of these units beingdisposed directly above each of the recesses 26 on the table 25.

f Supported overhead by a structure (not shown) is a series of emptycarton dispensers 42, one of which is located directly over each of therecesses 26 and is kept constantly lled with empty cartons properlymarked for receiving the grade of eggs being packed in cartons occupyingthat particular recess.

Each totalizer unit 4l is provided for the purpose "of actuating acounter during the pack-'4 ing of each individual lot of eggs so that atthe end of the packing of this lot, this counter will indicate thenumber of eggs of that particular grade with the packing of which thattotalizer is associated.

In practice, the counters 50 of all the totalizers lll are at a remotecentralized point and these counters are preferably of the printing typeso that a print may be taken from these indicating the totals of eggs ofeach of the various grades packed from said lot, these totals being thebasis for determining the purchase price to be paid the farmer for thislot of eggs.

Each totalizer unit il is mounted on a base having a motor standard 52as well as shafts 53,

56|, 55 and 56 fixed thereon and extending upwardly therefrom. Mountedon the standard 52 is an electric motor 51 having a shaft 58 carrying anarmature 59 and having mounted on its lower end a clutch 5e including aclutch member 6| which is fixed to the shaft, a spring 62 and a clutchmember 63 which is fixed upon a pinion gear 65| which is freelyrotatable on the shaft 56.

When the motor 51 is de-energized, the armature 55 drops into its lowerposition as shown in Fig. 6, thus disengaging the clutch 66. When themotor 51 is started, however, the armature 55 is lifted upwardly intocentralized relation with the motors field magnet 65 thereby engagingthe clutch Gli and rotating the pinion 6ft.

Held in place on the shaft 53 by a screw 1@ is a mandrel or secondarycontrol rotor 1| having a threaded neck 12 at its upper end, thejuncture of this neck with the mandrel providing a shoulder 13. rThemandrel 1| has a dog 1t pivotally screwed thereon by a pin 15.

Supported on the shoulder 13 and held in place by a nut 16 is a camsleeve 11 having a single cam 18 at a lower level and two cams 19 at ahigher level.

To illustrate the operation of these cams, the cam i3 is illustrated inFig. 8 as upon a separate element than the cams but this is merely toclarify their distinctive operation as all three of these cams areformed upon the sleeve 11.

lin Fig. 6 the cam 18 and one of the cams 19 are shown as if located 180apart. This is only a diagrammatic representation of these cams,however, for the purpose of showing their vertical spacng in thesectional view of Fig. 6. In reality the cams 19 are spaced apart anangle of 126 and the cam 18 is spaced the same angle from each of thecams 1S.

Rigidly fixed on the mandrel neck 12 by nuts 66 and El is an odd countselector 82. This has a shape of a bell, the outer wall 33 of which isdivided into thirty-six parts and carries three series of numerals Nfrom l to 12. The lower edge of the wall |53 is scalloped by theformation therein of a series of thirty-six depressions 34, the purposeof which will be made clear hereinafter. l

In addition to carrying the numerals N, the wall 83 is provided with arst dozens line 85 which extends entirely around the wall s3; a seconddozens line |26 which extends only twothirds of the way around thisWall; and a third dozens line |31 which extends only one-third of theway around this wall.

The cover for the unit d! has a front wall 85 having a window 59 thereinthrough which a portion of the selector 6?: extends. Supported on thefront wall 8S is a manual switch Q6, its opened position beingdesignated by the numeral 12 and its closed position being designated bythe numeral 36, these numerals being applied to the wall 66 as shown inFig. 3.

A pointer 9| depends from the upper edge of the window 86 pointing toone of the numerals N. A detent roller mounted on an arm 96, rotatableon the upper end of a post 91, is urged by a spring 96 into successivedepressions 84 in the rim of the wall 83 so as to cause the selector 82to halt with the pointer 9| pointing at a particular one of the numeralsN.

Rotatable about the mandrel 1|, and resting on the base 5|, is a gear|65 which has fixed thereon a triangular lue |65.

Supported on a bracket |01 and mounted on the base 5| is a secondarycontrol switch l, the switch arm |65 of which carries a ring H0, thelatter surrounding the mandrel 1| and resting on the dog 14. When thering lli) thus rests, as shown in Fig. 6, the switch |58 is closed. Whenthe gear |55 is rotated, however, to bring the lug |06 into engagementwith the dog 14, the latter is tilted, as shown in Fig. 7, therebylifting the ring is and opening switch |68.

Also mounted on the base 5| on a pair of posts are switches ||2 and H3.The actuating rollers ||ll and ||5 of these switches bear constantlyagainst the outer surface of the sleeve 11, the roller lf3 lying in thepath of the cam 18 and the roller ||5 lying in the path of the cams 19.

The switches H2 and H3 are normally closed. The cams 16 and 19 arelocated at circumferential intervals of apart and whenever one of thesecams engages the roller disposed opposite it, the switch having thatroller is opened.

Rotatable on the shaft 5d is a pinion I6 which meshes with the gear |5and has formed integral therewith a gear l|1 and a cam hub or rotarycounter actuator ||3 having four cams H9 extending radially therefrom.

Fixed on the base 5| is a counter switch |25, the actuating roller |26of which is yieldably pressed against the cam hub H8. This switch isnormally opened but is closed each time the roller |26 passes over oneof the cams |19.

Rotatably mounted on the shafts 55 and 56 are gears |21 and |25 whichare respectively integral with the pinions |29 and |35, the pinion |29meshes with the gear H1, the pinion |30 meshes with the gear |21 and thegear |21 meshes with the motor pinion 65. A gear train is thus formedwhich connects the motor 51 with the gear |05 whenever this motor isenergized.

As indicated in Fig. 8, there is a ratio of 1 to 9 between gear |65 andgear H1. While any suitable ratio may be provided by the gear train |3|between the gear l l1 and the motor 51, a suitable ratio has been foundto be 1:66.

Also mounted on the base 5| is a motor control impulse relay |35. rlhisincludes a mounting plate |36 which is secured to the base 5| and onwhich is fixed a vertical shaft |31. Freely rotatable on this shaft is aseven-tooth ratchet wheel |38. Mounted on the plate |35 on oppositesides of the shaft |31 are solenoids |69 and |46. These solenoids havearmatures |l| and |42 and springs M3 and Hit which hold these armaturesagainst stops M5 when the solenoids |39 and |40 are deenergized.

'Ihe armatures Mi and |42 carry dogs |46 and |41 which idle over theteeth of the ratchet wheel |36 when the solenoids |39 and |40 areenergized but which engage the teeth of the ratchet wheel and turn thelatter when the solenoids are de-energized and the armatures |4| 'and|42 are returned against the stops |45 by the springs |43 and |44.

Also mounted on the plate |36 is a spring actuated detent |50 whicheither rests within one of the notches between adjacent teeth of theratchet wheel 38 or comes to rest with one of said teeth entering anotch |5| provided in the end of the detent |50. The purpose of thedetent is to prevent rotation of the ratchet wheel |38 in acounter-clockwise direction. Mounted on the base 5| is a motor controlswitch |55 which is normally open and has an actuating arm |56 whichnormally extends into one of the notches of the ratchet wheel |38.

As the motor 51 is preferably run by a 28- volt circuit, a transformer|60 is shown in Fig. 8 as receiving current from 110 v. leads |6|.Secondary leads |62 and |63 from this transformer supply 28-volt currentto the unit 4|.

The lead |62 connects to one side of each of the following elements:switch 29, motor 51, switch 90, switch |3 and switch 25. The lead |63connects to one side of the following elements: counter 50, switch |08,solenoid |39, solenoid |40 and switch 55.

The other side of switch |25 is connected to counter 50; the other sidesof switches 90 and ||3 are connected to one side of switch 2; and theother side of switch ||2 is connected to the other side of solenoid |39.

The other side of switch 29 is connected to the other side of solenoid|40.

The other side of switch |08 is connected to the other side of switch|55 and to the other side of motor 51.

It is thus seen that the motor circuit may be closed either by switch|08 or by switch |55 and that both of these switches must be open tostop the motor.

Attention is called to the fact that in the diagrammatic View of Fig. 8,certain distortions of the apparatus occur for the purpose of presentinga simplified showing of the functions thereof. For instance, the cam 18is shown as on a separate element 11 from the cams 19 while these areactually all on the cam sleeve 11 and formed integral therewith.

The switch |55 is also shown diagrammatically in association with aseparate actuating cam, whereas it is actually actuated, as shown inFig. 4, by the switch arm |56 riding on the periphery of the sameratchet wheel |38 which is engaged by the dogs |46 and |41 and thedetent arm |50.

A further distortion in Fig. 8 may be seen in the representation adoptedtherein for the switch |08 in which this switch is shown as a wipingtype switch instead of a swinging arm type switch as clearly disclosedin Figs. 6 and '1.

Operation The counters 50, which are shown diagrammatically and in Fig.8 only, are centralized in a counter cabinet (not shown) and areprovided with printing faces from which an impression may be made on alot record card at the end of the packing of each lot handled by theapparatus so as to show the exact number of eggs taken from said lot andpacked in each of the stations 26.

While only four sizes of eggs are delivered on the conveyor Il, thepacker is required to candle the eggs before a candling light |10mounted on the packing table 25 and make two additional egregationsbased on quality thus disclosed so that there are six distinctive sizesand grades packed on this apparatus.

The operation of each unit 4t and its counter 50, however, is the samefor each of these packing stations and a description of the operation ofone of these units will suiiice for all.

Assuming that the cartons 21 are standard dozen cartons, the unit 4| forany given packing station is caused to actuate its counter 50 twelvetimes when a packed carton is moved from that station rearwardly ontothe packed carton conveyor 28. The unit 4| performs this function inresponse to the momentary opening of the switch 29 of that unit as thefilled carton 21 is moved thereover. An empty carton is then withdrawnfrom a supply chute directly above this station and placed over switch29 in that station.

When this second carton has been lled, it is pushed rearwardly on theconveyor 28 in the same manner as the first, with the result thatactuation of the switch 29 causes the unit 4| for this station to againactuate the counter 50 thereof twelve times.

This continues throughout the packing of the particular lot of eggsbeing handled by the apparatus. At the conclusion of the packing of thislot, a lot card arrives on the conveyor with the name on it of thefarmer from whom this particular lot of eggs had been purchased.

The operator thereupon actuates each of the units 4| so that these unitswill actuate their respective counters 50 to add to the totals shown bythese counters the number of eggs contained respectively in the sixincompletely packed cartons in the various packing stations 26.

When this has been done, the operator inserts the lot card into positionto receive an imprint simultaneously from all of the counters 50 showingthe total number of eggs packed from this particular lot in each of thestations 26.

This having been done, the counters 50 are set back to zero and theoperator is ready to start packing on a new lot of eggs which now startsto arrive on the conveyor t.

The first part of this new lot of eggs is used to ll up the cartons 21which were incompletely lled at the close of the packing of the lastprevious lot. It is one of the advantages oi the present invention thatas the packing of each of these partially filled cartons 21 is completedand it is pushed backwardly onto the conveyor 28 so as to trip theswitch 29 therebeneath, the totalizing unit 4| for that packing stationautomatically actuates the counter |50 associated therewith a number oftimes equal to the number of eggs which were added to this carton fromthe new lot, the packing of which has just been started, in order tocomplete the packing of that carton. When the next succeeding cartonpacked in this particular station, however, has been lled entirely fromthis new lot and is pushed rearwardly so as to actuate its switch 29,the unit 4| for this station automatcally actuates its counter twelvetimes.

It is thus apparent that the only attention which the operator must payto the units 4| to cause them to accurately totalize all the eggs packedfrom each lot in the stations respectively associated with said units,is in setting these units to add to their respective counters the numberof eggs respectively contained in the partially lled cartons remainingat the end of the packing of a given lot.

The manner in which any one of these totalizer units 4| accomplishesthese functions is as follows:

Assuming that dozen cartons are to be employed in packing eggs in theapparatus l0, the switches 90 of all the units lli are turned to twelveat the beginning of the packing day and the pointer 9| of each of theseunits points to one of the numerals 12 on the selector 82 thereof.

At this time, in each of the units M, the lug |08 is pressed against thedog 'i4 so as to cock this upwardly as shown in Fig? thereby opening theswitch |88 and assuring that any anti-clockwise rotary motion ci thegear |85. will be transmitted to the mandrel 'il and the cam sleeve 1l.

When the operator has completed packing a carton at the station for theparticular unit 2|, the operation of which is being described, shepushes this rearwardly onto the packed carton conveyor belt 28 therebytripping the arm 38 and momentarily opening the switch 29.

As the solenoid |48 is constantly energized, excepting when the switch29 is thus tripped, the dog |41 is ordinarily in its position ofreadiness (shown in full lines in Fig. 8) so that when the solenoid |48is thus momentarily deenergized, the spring |44- pulls the dog |4i intoits dotted line position in this view, thereby rotating the ratchetwheel |38 one-fourteenth of a revolution.

This brings one of the teeth of the ratchet wheel directly under the tipof the arm |55 of the switch |55 thereby closing this switch andstarting the motor l.

The rising of the armature 59 of the motor 5l as it is energized, closesthe clutch 8E and starts the gear train |3I in motion. This turns thecam hub ||8 and as each of the cams H9 cornes opposite the roller |25 oithe switch |25, it closes this switch causing a single actuation of thecounter 58.

The gear |85 is also rotated by the gear train at a ratio of once foreach nine revolutions of the cam hub |I8. This rotates the mandrel 1|,the cam sleeve ll, and the selector 32 one-third of a revolution or 120while the switch |25 is being actuated twelve times.

The detent roller 95 rides from one depression 84 to the next as thisactuation of the counter takes place. One of the cams i8 or 19 comesopposite the rollers IIS or H5 respectively of the switches ||2`or |I3just as the counter 5|] has been given its twelfth actuation so thateither the switch I|2 or the switch ||3 is opened. As both of theseswitches have been closed during the rotation of the cam sleeve llincidental to these twelve actuations being imparted to the counter 50,the solenoid |39, during this period, is energized to retract .the dog|86 into the dotted line position in which it is shown in Fig. 8. Thisbrings this dog closely behnd one of the teeth of the ratchet wheel |38and when the solenoid |39 is de-energized by the opening of one of theswitches ||2 or ||3 as hereinabove noted, the spring |43 operates topull the dog |48 against this tooth of the ratchet wheel |38 so as toimpart to the latter another one-'fourteenth of a revolution. lThisbrings one oi the valleys between adjacent teeth of the ratchet wheel|38 opposite the extremity of the arm |55 of the switch |55, as shown inFig. 4, so as to open this switch thereby de-energizing the motor 51.

Immediately upon this happening, the armature 59 drops by gravity to theposition in which it is shown in Fig. 6, thereby opening the clutch Biland halting movement of the gear train I3I. The lodging of thedetentroller 95 in thedepression 84 into' which it rides as this takes place,indexes the gear train |3| and the selector 82 with the pointer 9| againpointing at one of the numerals N with a value of twelve.

The operation of the unit 4|, as just described, is repeated to add avalue of twelve to the counter thereof by each subsequent operation ofthe switch 29 incidental to moving a fully packed carton rearwardly fromits station 26 onto the packed carton conveyor 28.

When all the eggs from the lot being handled are packed and the cartonin the station 26 for the unit 4| being discussed is only partiallyiilled with eggs, say, for instance, that it contains only seven eggs,the operator places her hand on the wall 83 of the selector 82 androtates the latter in an anti-clockwise direction until the numeral Nwith a value of seven comes opposite the pointer 9|. The detent roller95 holds the selector 82 with the pointer 9| precisely aligned with thisnumeral when the hand of the operator is removed from the selector.

When the operator starts to turn the selector 82, this also turns themandrel 1| and cam sleeve l'i which moves the dog 14 out of contact withthe lug |86 causing this dog to rock into horizontal position (as shownin Fig. 6) thereby closing switch |98. This starts the motor 51 runningwhich sets the gear train |81 in motion and causes the rotation of camhub ||8 and the successive closing of the switch |25 and actuation ofthe counter 58 as long as the gear train continues to move.

The shifting of the selector 82 to bring the numeral 7 opposite thepointer 9| results in the lug |96 reaching the dog 14 so as to cockthis, open the switch |88 and halt the motor 5l just as the counter 58has been actuated seven times.

As this operation occurs at the end of a run, the counter 58 is turnedback to zero before this unit 11| is again actuated and the next time itis actuated will be when iive more eggs have been placed in thepartially packed carton in the station 2t with which this unit isassociated, so as to complete the packing of that carton. This done, theoperator pushes the packed carton back onto the packed carton conveyor28, thereby momentarily opening the switch 29.

This temporarily de-energizes the solenoid |40, permitting the spring|44 to impart a one-fourteenth revolution to the ratchet wheel |38 which`closes the switch |55. This causes the motor 51 to drive the gear trainI3! to actuate the counter 5|) until one o the cams 'It or 19 comes incontact with one of the switches I|2 or ||3 respectively and opens thecircuit of the solenoid |39 permitting the spring |44 to impart anotheronefourteenth revolution to the ratchet wheel |38, and shut off motor5l.

Owing to the fact that before the switch 29 is thus momentarily opened,the sleeve 'Vl had already been turned seven-twelfths of away fromcoincidence between one of the cams 'It or 'E9 and one of the switches|I2 or |I3, another one or" these cams i8 or '|9 will thus come intocoincidence with one of the switches |I2 or |I3 after the cam sleeve l1has rotated only fivetvvelfths of 120, This amount of rotation iseffective in causing the actuation of the counter 58 ve times before theopening of one of the switches ||2 or H3, which causes the switch |55 tobe opened and the motor 51 to be de-energized. I

When the gear train ISI is thus halted, the selector 82 has been movedto again bring a numeral N with a value of 12 opposite the pointer 9|and the unit 4l is now set up so that with each of the subsequentmomentary actuations of the switch 29, this unit will add a value oftwelve to the counter 50.

The units 4| are also adapted for use in connection with packing casefillers each of which will hold three dozen eggs. When such case fillersare used, the switches 90 of the units 4I are swung over to 36 which, asmay be seen in Fig. 8, means the closing of these switches, therebycutting out the switch H3 from playing any part in stopping the motor51.

With the switch 90 thus closed, the counter 50 will Vbe actuatedthirty-sixtimes each time the switch 29 is momentarily opened and theselector 82 may be manually operated to indicate any whole number ofeggs less than thirty-six and the unit 4| will proceed to actuate thecounter 50 a number of times equal to the number of eggs thus designatedby the selector 82.

In a like manner, after this has been done and the switch 29 is againopened momentarily as by the discharge of the completely packed casefiller, the counter 5l! will be actuated a number of times whichrepresents the difference between thirty-six and the number less thanthirty-six previously indicated by the counter Sl in order to add to thecounter 50 a number equal to the eggs contained in a partially packedcase ller.

The term normal cycle may be used to refer to a cycle of operation of atotalizer 4l which is started by actuation of the switch 29 for thepurpose of counting all the eggs in a full carton. Such a cycle willnecessarily start with the selector or linger dial 82 positioned withone of its numerals 12 opposite the pointer 9| as shown in Fig. 8, andif the standard number being used is 12, either the switch H2 or I i3would have to be open at the start of the cycle. If the standard numberbeing used is 36, the switch 90 would have to be closed and the switchH2 open at the start of the cycle in order for the latter to come underthe term normal cycle as herein dened.

For convenience, the cycle of operation of the totalizer 4l effected bymanipulation of the selector 82 to count the eggs in a partially lledcarton may be referred to as a selective cycle.

The counting cycle which takes place upon the switch 29 being nextopened following a selective cycle and in which the number of eggsrequired to completely fill the partially filled carton is counted, maybe referred to as a remainder cycle as it effects the actuation of thecounter a vnumber of times equal to the remainder produced bysubtracting the number of actuations produced in the selective cyclefrom the standard number being used at that time.
